A lightweight open framework for building fast and efficient cloud-native Java microservices.
Build cloud-native apps and microservices while running only what you need. Open LibertyTM is the most flexible server runtime available to JavaTM developers in this solar system.
Develop cloud-native Java microservices
Open Liberty starts up fast, with a low memory footprint and live reload for quick iteration. Adding and removing features from the latest versions of MicroProfile and Jakarta EE. And with zero migration, you focus on what's important, not the APIs changing under you.
MicroProfile
Dev mode for fast iteration
Launch into dev mode and get coding. No more manual compiling, packaging, and deploying—we handle that for you. Get automated testing, debugger support, and a fast turn-around time in any editor.
Deploy in containers to any cloud
Containerized and deployable with fast throughput on any Kubernetes cloud. Battle-hardened and proven in production, with zero migration. Easy-to-manage configuration from development to test to production.
Monitor microservices in the cloud
Trace your live microservices. Gather metrics and configure alerts, and browse metrics in dashboards. Consolidate and analyze logs from across your hybrid cloud.
